A single turbo N54 engined E90 3 Series is finally alive! HorsepowerFreaks recently fired up a forum member’s E90 335i with their HPF turbo system. Currently on the 335 is a Precision 6265. This N54 car has the HPF front mount intercooler, Evolution Racewerks BOV pipe with HKS BOV and the HPF exhaust. It is also running a Vishnu Procede and AEM gauges. Dyno results will be in soon, so stay tuned.
AR Design provides an update on its single turbo N54 kit, and the power numbers have gone up as expected. The latest dyno results are inside, corrected for 5700ft elevation.
Single turbo kits have been the vaporware of the N54 tuning world – often started but seldomly finished. AR Design gives hope with preliminary results of their single turbo N54 which has hit 444whp@15psi on a Mustang dyno, all on pump gas and no other FI methods!
